Magnitude, in Dollars, of Race and Sex Coefficients by Regression Model *
all female employees * All coefficient values shown were statistically significant at a 1 percent alpha-level. + The coefficient was not statistically significant at a 5 percent alpha-tevel. # No race and sex variables were used in these models.
sex, we must make the following adjustments if the employee
is not a white male:
(1) subtract $5,119 if she is a black
female, (2) subtract $4,131 if she is a white female,
(3) subtract $3,729 if she is a nonblack minority female,
(4) subtract $3,085 if he is a black male, and (5) subtract
36/ $1,178 if he is a nonblack minority male. And these
differences are after any differences in age, education,
and length of government service have been accounted for.
The salary gap is thus seen to be nearly as large as when
the other explanatory factors are not considered.
Finally, consider an employee who joins the Department
of Labor at age 25 with a bachelor's degree.
is now 30 years old, possesses 5 years of government exper
ience, and has earned graduate credits equivalent to another
year of education. We can use the various regression models to predict the employee's salary, as follows: 37/
The result given for a nonblack minority male was not statistically significant at a 5 percent alpha-level.
37/ The regression models for sex within race were used to develop this comparison. They were used as outputted by the regression program; that is, before elimination of any of the variables. For purposes of the comparison, the employees were assumed to work for either ESA or LMSA in the National Office, although similar results would have been obtained from other assumptions.
Much of the time that was available to do the corre
lation analysis was used in setting up the problem and
obtaining successful computer runs.
The analysis accom
plished to date has not begun to exhaust the possibilities.
The problem documentation, the computer output to date,
the data itself (ready for any further computer runs), and
the regression routine are all available to interested
